MACHINE FOR FOLDING AND PASTING PASTEBO ARD. BOXES- n seaaae.

Patented Oct. 16, 1906.

Application filed August 1, I904. Serial No. 219,06 8.

To all whom it may concern:

Be it known that I, JOHN W. Low, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Imrovements in Machines for Folding and asting Pasteboard Boxes," and I do hereby declare that the following is a full, clear, and

exact description thereof, reference being had to the accompanying drawings, and to of reference marked thereon, which form a part of this specification.

This invention relates to improvements in machines for folding and asting asteboard boxes or cartons, the box ein fo ded from a fiat, properly cut, and score blank to tubular form and pasted at its meeting edges while fiat and thereafter opened into tubular form to constitute the carton or box.

Among the objects of the invention is to simplify the construction and operation of a machine for this purpose and to increase the capacity of such machine, and thereby reduce the cost of operating the same and the cost of the folded and pasted boxes.

As shown in the drawings, Figure '1 is a plan view with parts broken away of amachine for the purpose set forth made in accordance with my invention. Fig. 1 is a section taken on line 1 1 of Fig. 1. 2 is a vertical longitudinal section of the machine. Fig'. 3 is a vertical transverse section taken on line 3 3 of Fig. 2. Fig. 4 is a vertical section and elevation taken on line 4 4 of Fig. 1. Figs. 5, 6, '7, 8, and 9 indicate the steps which the blank assumes while being formed into a box, said views being taken on lines 5 5, 6 6, 7 7, 88, and 9 9 of Fig.1.

The lparticular folding and pasting machine il ustrating one embodimentof my invention embraces in eneral terms a wide l t trained about suitable ulleys and constitutin the sup ort for blanks as they pass through t e machine and two endless formin -belts located one at each side of and'trave ing for a distance in contact with the forwarding-belt and preferably at an equal speed therewith.

The said forming-belts in the parts thereof which travel in contact with theforwarding and supporting belt are twisted in a manner to give the same a spiral or plowshare form thereto, so that as the blanks are carried along between the forwarding and supportthe machine and are given ing belt beneath and the formin -belts above the side sections or margins of t e blank are folded toward each other and one upon .the other.

Near the feed end of the machine is located a pasting device by which is applied to one of the sections of the blank a strip of paste by which the margins of the blank are pasted together when the blank has been folded flat. The .machine ,is preferably made adjustable to operate on blanks scored to produce various size boxes.

The machine is herein shown as adapted for folding and pasting from flat suitablyscored blanks elongated tubular cartons of rectangular cross-section. A machine for folding such boxes and the manner of folding the box is shown in the prior patent granted to myself and Roy J. Carrier, No.

705,206, dated July 22, 1902. The blank from which said box is made consists of a single piece of sheet materialwhich is scored to form four parallel sections, one for each of the walls of. the tubular b oxwvhen formed,-

and the two side sections are first folded upwardly, While the intermediate sections remain flat, said folding side sections being folded toward each other with the margin of one overlappingthe margin of the other, to

the lowermost one of which overlapping margins has previously been applied a strip of aste.

eferring now to the particular machine 'in which my improvements are shown as embodied, the frame consists of two side parts embracing longitudinal, horizontal, and vertical members A A, joined by transverse members. (Not shown.)

B designates an endless belt, the upper lap of which constitutes the support for the blanks as they pass through form. Said belt or conveye'r is trained about horizontal pulleys B B, the shafts b of which are rotatively mounted in bearings a on the upper longitudinal members of the machine-frame. Said belt is driven by power applied through the medium of fast and loose-pulleys b b on one of the shafts b of the pulleys B. The upper lap of the forwarding and supporting belt is ireferably supported by a flat horizontal board B conslderably wider than the belt, and said board is supported on the upper loi1- gitudinal members of the frame through the wide forwardingmedium of vertical cross-bars B. (Shown 'in Fig. 2.)

cated at the level of the u per laps of the. forming-belts at the feed en of the machine, said upper laps of the forming-belts being at versely across the machine and which is C C designate the forming-belts, located nearthe side margins of the upper lap of the forwarding-belt, Figs. 1 and 3, and traveling in contact and in the same direction therewith and preferably at the same speed. Said forming-belts are trained about pulleys A A and A A mounted on shafts a a, which have suitable bearings in, the side members of the machine-frame. each end of the machine, are located at such level as to bring the upper laps of the forming-belts at a height to travel in contact with the forwarding and supporting belt B, as before stated.

D designates a horizontal feeding-table 10.-

this place horizontal.

E E designate a pairof feeding-belts the lower laps of which travel for a short distance in contact with the horizontal parts of the -upper laps of the forming-belts at the'feed between which belts end of the machine and the blanks are received and carried into the machine. Said feeding-belts E are trained about rotative pulleys E E, the horizontal transverse shafts e of which are mounted in suitable bearing in the machine-frame. Said pulleys E E and the pulleys A A are movable longitudinally of. their shafts, whereby the forming and feeding belts may be moved toward and from each other to adjust the machine to Wider or narrower blanks, as desired. The said forming-belts extend at both the forward and rear ends of the machineforming-belts C are turned or twisted one-v half round, thereby giving to the same a spiral form and which acts upon the side secgaged by the pulleys and to rise.or

tions of the scored blank, hereinbefore referred to, to fold the same, first upwardly, then toward each other, and, lastly,-down- 'wa'rdly one over theother in overlappingcontact. The said forming-belts are thus twisted bymeans of suitable pulleys engaging the same at different parts of their length. The parts of the forming-belts passing beneath the feeding-belts E are flat. Located in front of said feeding-belts are two pulleys F F, which rotate on vertical axes and are carried b horizontal blocks F, which are su porte on the horizontal board B, before Said pulleys F cause the belt to points en- 0 twisted gradual from a horizontal to a vertical position between the feed-belts E and pulleys re erred to. assume a vertical position at the F. Located in front of said pulleys F are- The pulleys A, one at.

another pair of pulleys G G, which rotate on horizontal axes and are rotati-vely mounted on the inner ends of horizontal blocks G, that are fastened to the upper face of the support or board B for the belt. Said pulleys G engage the upper margins of the formingbelts in a manner to turn the same from the vertical positions into which they are brought by the pulleys F toward each other at their upper margins, and thereby assume inwardlyinclined positions. Inasmuch as one side section of the blank should be turned inwardly and downwardly before the opposite section in order that there be no interference shown in Fig. 1. Said forming-belts C are brought to horizontal fiat positions by means of pulleys H H, which are affixed to a transverse horizontal shaft H, that extends transmounted in suitable bearings in the side members of the machine-frame. Said pulleys H therefore rotate about a horizontal axis and press the forming-belt flatwise against the forwarding and supporting belt B. From the pulleys H the forming-belts O retain their flat horizontal positions to the pulleys A at the ends of the machine and retain such positions over the pulleys A A and ,back to the pulley A at the feed end of the machine. I

Located at the inner margins of the formin -belts from points adjacent to thcjeedingbe ts E and extending forwardly to the neighborhood of the vertical guide-pulleys G are two parallel bars I I. Said bars are fixed to the lower ends of vertical rods I I, there being two rods associated with each bar, as herein shown, one attached near the rear and the other near the front end of the bar. Said rods I are provided at their upper ends with heads i i, which are provided with transverse a ertures that slide on two horizontal parailel rods I I, located transversely above the belts B and C and attached in any suitable manner to an overhead part of the machineframe. As herein shown, said rods 1 are attached to vertical bars I, Figs. 2 and 3, which latter are attached at their upper ends to and de end from a centrally-located longitudina ly-disposed beam A, that extends between and is attached at its ends to trans- 1 warding and forming bolts and supported on Lll fore referred to.

the upper ends of extensions A of the vertical members A of the machine-frame. The said bars I are so located that the planes of the outer surfaces thereof are in line with. the score-line's between the outer folding sections of the blank and the intermediate flat sec tions. 1 The blanks are fed beneath the rear ends of said bars and between the sameLand the forwarding-belt; the forming belts begin to turn or twist, however, due to the action of the pulleys F, they fold the. outer sections or flaps of .the blank upwardly about the inner surfaces of thebars Inntil said folding sections or flaps assume vertical positions, which occurs justbefore the blanks reach the guide-pulleys F. The bars serve -.not only as means affording vertical surfaces about which the side or folding flaps are folded, but alsoas means serving toprevent the blank from rising-off the forwarding andsupporting belt. Said bars follow the belts 1G to the point where the belts pass from a vertical to an inwardly-inclined position, and

- thereafter the inclination of thebelts folds the fla s inwardly; and it is prevented from rising y the overhanging of the inwardlyinclined parts of the belts.

In order to prevent the intermediate parts 1 or sections of'theblank from rising while the outer sectionsor fla s are being folded upwardly and inwardy in the manner described, I may employ a series of presserrollers J J ,rotative y mounted on. a seriesof horizontal studs 7', that are fixed in a horizontal longitudinally-arranged bar J, that is attachedat'its end to the vertical bars 1 be The forming-belts andthe parts asso- .ciated therewith tofold the guide margins or flaps of the blank. as they are assed through the machine are arranged to e adjusted to fold boxes ofdiiferent widths. For this purpose the blocks' F G, carrying the belt-directing pulleys F and are attached to the support B by means ermitti' the sameto be moved toward an from eac other. As

herein shown, said blockslare attached to the support by means of set-screws g, extending through elongated longitudinal slotsin the blocks. The bars I Tare similarly designedto be moved toward and: from each other to follow the forming-belt, and for this purpose the, apertured'heads "i, by; whichsaid rods I" are attached to the-horizontaltrans' verse rods 1 have sliding engagementwith are also adjustable lo itudinally of their shafts and are at-tachedt ereto by set-screws in the manner shown, whereby they maybe nov'e'd towardand from each other'to correforming-b elts.

Said paste-applying disk is fixed to a horizontal rotative shaft k, parallel with and above the shaft is. k k designate disks and prevent the accumu ation of paste thereon in a manner to apply paste irregu larly to .the blanks as they pass thereoverl The 'said aste-receptacle K is made of con-: siderable ength transversely of the machine, and thedisks K K are ada ted to' be. adjusted longitudinally of their s a'fts b means of the set-screws shown, so that sald disks will always be in roper osition to'apply thepaste to the blan in al lateral adjustments of the machine. The shaft k, on which the paste-applying roller is mounted, is geared to the adjacent shaft 0/ to im art rotation to saidpaste-applying disk an its shaft-l The driving connections between the shaft 0/ and the shaft. k of the said paste-applying disk consists-of a sprocket-chain k trained about After the marginal flaps of the blank have been pressed downwardly upon each other they are passed beneath a pressing-roller H that is mounted on the shaftH and pressedbetweensaid roller and the forwarding-belt B.. The folded shell after passing between said nr;essing-roller H and belt B? passes'between. squeezing-rollers L L located one over the other in front ofand line with the roller H and the pasted joint is assed between said squeezing-rollers to furt er setthe joint. Said rollers are mounted on horizon-- tal shafts Z Z, that extend transversely across loo given rotation.

A.slanting receiving-board M is provided at the dischargeend of the machine, located just in front of the squeezing-rollers L L and upon which the folded boxes are discharged.

. Said board is provided with a stop consisting of brackets M M, rising vertically therefrom at the lower side thereof. A weighted lever N is provided, which is loosely or rotativel connected with a transverse horizontal sha t "N', that extends across and has bearing in the side members of the machine-frame in front of the squeezing-rollers. I The forward or free end of said bar N is ada ted to press downwardly on the bundle of olded boxes,-

which accumulate upon the receiving-board M, and said lever is weighted, so as to hold the folded'boxes in a compact bundle until removed from the machine. The stop-brackets M are separated, so as to permit the lever to be made sufficiently long to-engage the folded boxes near the lower edges thereof and still permit said lever to be swung u wardly as the bundle increases by the ad ition of I boxes thereto.

sive. In Fig. 5 the blank is shown in its fiat position wh le passing between the feedingpath of movement ally-a djustable gage-plate D upper. margin The feed-board D is provided with a later located at one side of the path of the blanks as they are fed the margins of the blanks an enables the blanks to be properly fed into the machine, so that the score-lines about which the side sections or flaps are folded u wardly are brought into register with the si e margins of the bars I without special care being required of the operator to effect this result.

. The stages by which the marginal sections or flaps of the blank are folded u wardly to bring the box into its closed or tu bular form as it passes through the machine are indicated-more clearly 1n- Figs. 5 to 9, both inclubelts E and the forming-belts C. s In Fig. 6 is shown the position which the side sections or fla s assume with respect to the forming be ts and to the bars I as soon as the formingbelts begin to turn toward vertical positions. In Fig. 7 is shown theposition of such parts when the blank has reached that part of its are vertical. In Fig. 8 is shown the position of the blank and the forming-belts after the of the forming-belts begin to turn toward each other and downwardly against the supporting or forwarding belt B, and in Fig. 9 1s shownthe position of the blank and the belts after the forming-belts Said gagelate engages when the f0rming-belts ceases upon the forwarding and supporting belt B.- In this figure is also shown the pressing-roller H relatively to the asted joint of the box. In this manner it wil be seen that the transition from a flat blank to a asted tubular box or shell is continuous and be further observed that by reason of the fact that the forming-belts travel with the su porting and forwarding belt and preferthe mar inal flaps is accomplished ractically witIiout friction between the be ts and the blank or shell. For this reason less power is required to direct the blank or shell through'the machine, and there is less liabilltyrOf' the blank or shell sticking chine by reason of undue friction, such as would be true if the forming parts were stationary and the belt B or equivalent part were movable. The machine herein shown is exceedingly simple in its construction and t e same, and is free from complex mechanisms which are likely to get outof order.

While I have herein shown a form of ma-- chine embodying the improvements constituting my invention which I have found to be commercially practical, yet itis to be 1111-, derstood that my invention may assume widely different forms, whileretaining the essence or s irit thereof. I do not wish, therefore, to be limited to the particular conmade the subject of specific claims.
